How to Implement Personal Configuration roaming in a domain Q: the company has a local area network, the server side is Windows 2000 Server Client is Windows 2000 Professional, and a computer sharing zone is built. That is, No matter on which computer you use your account, you can obtain your previous configuration. USER environment, such as desktop, my documents, etc. C: all configurations under/Documents and Settings/% username %. After a user is enabled with a roaming user configuration file, the above functions can be implemented on some computers. But on some computers, all the required files are roaming (except C: /Documents and Settings/% username %/Local Settings/Application Data/personal folder in Microsoft/Outlook *. pst. I have previously set up a Server Policy Editor. Do I know if it is related to this ﹖ A: To solve this problem, you need to use the "Folder Redirection" function in the Group Policy of Windows 2000 Server. Assume that the Windows 2000 Server domain name is msft.com and the computer name is w2kser. Create a directory such as public in the NTFS partition and set the sharing name to public. The folder permission and sharing permission are fully controlled by the Everyone user group. Go to "Active Directory users and computers", right-click the domain name msft.com, select "properties" from the menu that appears, click the "Group Policy" tab, and select "default domain policy ", click "edit" and click "user configuration> Windows Settings> Folder Redirection ". You can see four options. Right-click Application Data, select "properties" from the menu that appears, and select "Basic" from the right of "Settings, redirect everyone's folders to the same location, and enter // folder in the target folder location. Click OK. Then, redirect "desktop" to // w2kser.msft.com/public/?username=/topics top,“my documents "to // users. You can also create an ou in msft.com, for example, your organization name, move all users in the enterprise to the new ou, and then create and edit group policies in the new ou. Windows 98 machine cannot renew domain Q: Local Area Network machines coexist in Windows 98, Windows 2000, Windows XP, and other operating systems. The domain is ztyb.com. A Windows 98 computer automatically logs on to the machine every time it is started, but instead of logging on to the domain, it logs on to the local machine. How can this problem be solved? A: Right-click "Network Neighbor" on the desktop and select "attribute" from the menu that appears (or double-click "network" from "Control Panel ), double-click "Microsoft network user", select "log on to Windows NT domain" from the displayed Properties dialog box, and enter ztyb.com under "Windows NT domain, click OK to return to the Network Properties dialog box. Select "Microsoft network user" from the list under "primary network login", click "OK", and restart Windows 98 as prompted. The system prompts "Security Operation" when adding the domain" Q: I have created a Windows 2000 Domain Server, but when the client is added to the domain, it sometimes prompts "Domain running in security operation status ". What is the problem? A: When you join a Windows 2000 domain, you should enter the NetBIOS Name of the domain (for example, if your domain name is msft.com, you should enter MSFT) instead of the full name of the domain, most of this problem occurs when the Windows XP Client is added to the Windows 2000 Domain. This problem is usually not found when Windows 2000 is added to the Windows 2000 domain. Nic error at startup Q: The following information will always appear on my computer: Intel undipxe-build 082 Copyright c 1997-200 Intel Corporation For RealTek rtl8139a/B/C/rtl8130 PCI Fast Ethernet controller V2.110012105 Client Mac addr00 E0 4C B3 32 FC GUIDFFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF DHCP ..... PXE-E51NO DHCP or proxydhcp offers were received ed PXE-MOFEXITING PXE Rom. What is going on? A: This is because your Nic has enabled boot ROM chip Boot, And the NIC has a PXE boot chip. It can be solved as follows: ① If the NIC is integrated on the motherboard or the boot program on the internet is written into the bios, you can modify the boot sequence of the system from the BIOS settings, such as setting the hard disk to boot first, or, disable the NIC from starting the system from the BIOS. ② If the NIC is not integrated, You can unplug the boot chip on the NIC or use the NIC setup program to disable the bootrom boot function of the NIC. After the NIC is started, when press Shift-F10 configure... appears ......" Immediately press SHIFT + F10 to enter the menu, set boot order Rom to disable from row 4th, and press F4 to save and exit. Shared Internet access cannot browse webpages Q: After using Windows XP as a proxy server, I found that other computers in the LAN could not browse the webpage. However, if there is data flow, I can also use QQ or other software, and machines in the network could also access each other. The proxy server is a dual nic. in the Network Configuration Wizard, set it to "other computers in the network access the Internet through the Local Computer" (connect to the LAN through a NIC ), in the shared property, set it to "B connection shared to the network" (that is, 2nd, B Nic ). The client is set to "access the Internet through another computer in the network". The operating system has Windows 98/2000/XP and is connected through a switch. The indicator lights on the proxy server are working properly (A, B, and broadband modem connections), but the indicator lights on the client occasionally. When you open a webpage, you can see the "opening the *** webpage" in the status bar, but you cannot see the webpage for a long time. The prompt "the webpage cannot be displayed" is displayed. A: there may be a problem with your network connection and DNS settings: ① Establish a cascade line and connect network card a directly to the broadband ADSL. ② Set the IP addresses of other clients to 192.168.0.2, 192.168.0.3, 192.168.0.4 ......, Set the subnet mask to 255.255.255.0, set the gateway address of each client to 192.168.0.1, and set DNS to your ISP's DNS address. At the same time, you can also consider whether there is a conflict between the NIC of the proxy server, change the PCI slot, remove unnecessary peripherals, and so on.

The time difference between the server and some terminals (the operating system is Windows 2000 Professional) is always 13 hours, but the server time is accurate. When you click a terminal whose operating system is Windows 2000 Professional in the network, the system prompts "the server clock is inconsistent with the master Domain Controller Clock" and cannot be connected, you can connect to the Windows 98 operating system by clicking the terminal. How can this problem be solved? A: Check whether the time zone settings of Windows 2000 Professional are consistent with those of Windows 2000 Server. Select the "Time Zone" tab from "Control Panel> date/time" in Windows 2000. The time zone of the workstation is the same as that of the server. We recommend that you select "GMT + 0800 Beijing, chongqing ......". If this is not the case, run the net time command on the workstation for manual time synchronization. Who is logging on to my machine? Q: I have encountered a problem recently. When I shut down a computer, the system always prompts "another user is logged on to this computer". What is the problem? What should I do? A: Someone else connects to your computer through a network neighbor or other means. 1. All shares on your computer can be deleted. 2. Install a firewall software. disable port 139. 3. If your system is Windows XP, enable the firewall built in Windows XP.             Unable to log on to the network after power failure Q: The company's client (Windows 2000 Professional logged on to the server (Windows 2000 Server) when you want to see the shared files of other clients, the error "the simulated token for the thread graph operation of the customer is not simulated currently" appears. After the system is reinstalled, the problem is temporarily solved, but the process of re-login to the server from the client is not long after a sudden power loss, after logon, the error "No Logon Server is available to serve the login request" appears when you view the shared files of other clients. How can this problem be solved? A: You can solve the problem as follows: On the server, open "service" from "Administrative Tools" and check whether the "Remote Procedure callrpc" service has been stopped. If it is stopped, right-click it, select "start" from the menu that appears, and then start the service (but make sure that you have done a good job of preventing the shock wave virus before doing so ). You also need to check other items in the "service" to see if the "Startup Type" is marked as "automatic", and its "status" shows that if it is not "started ", start them. Run the chkdsk C/F command to check and repair the disk. Run the SFC/scannow command to check the system file. If the system file is damaged, reextract the intact system file from the installation disc to overwrite the damaged file. The Intranet website cannot be accessed normally. Q: The intranet of a company often encounters a situation where the network can be pinged and the network neighbors can be used normally, but the webpage cannot be opened when the Intranet website is accessed. Is there a good solution for this? A: The network can be pinged and the network neighbors are normal. This indicates that the network is good. The problem lies in the computer where the web page is stored. When the webpage cannot be opened, check whether the Web server is normal on the computer where the webpage is stored. If the server is Windows NT or Windows 2000, check whether the Internet Information Server is working (or started) and whether there is a problem with Web Sharing. If not, just delete the Internet Information Service, restart the server, reinstall Internet Information Service, re-create Web Sharing (the directory where the web page is stored), or re-create a website.

Reply: Always happy (posting: Level 5 member credit: 120 points: 2200) 2005-1-22 9:51:22 The network path cannot be found. Q: A small LAN is built on two computers. The operating systems are Windows 2003 Server and Windows 2000. After the connection and settings are complete, you can search for Windows 2000 machines on Windows 2003, but if you want to enter this computer, the message "network path cannot be found" is displayed, indicating that resources cannot be shared. What should we do? A: To share resources between Windows 2003 and Windows 2000, pay attention to the following points: 1. Do not enable "Internet Connection Firewall" on Windows 2003. If you install other firewalls, do not use the default settings. Otherwise, you cannot share resources with other computers on the network. When you Access Windows 2003, The system prompts "the network path cannot be found". It is likely that ICF is enabled. 2. You can search for a Windows 2003 computer, indicating that there is no problem with network connectivity. However, the system prompts "the network path cannot be found" during access, or the resource sharing settings may be incorrect. Check whether "Microsoft Network files and printer sharing" is selected in the "local connection" attribute ". If it is enabled and cannot be accessed, check whether the system is infected with viruses. 3. When Windows 2000 accesses resources in Windows 2003, you must add users in Windows 2003, set shared folders, and grant corresponding access permissions. On the contrary, Windows 2003 accesses Windows 2000. In general, if only two machines are running, they all use the system administrator account administrator) and set the password to the same. When entering Windows 2003 and windows, you can log on with the administrator account. 4. we recommend that you use automatic IP address acquisition in both Windows 2000 and Windows 2003, or use the IP address of the same IP address segment and set the same subnet mask to avoid various connectivity failures caused by IP address problems.             Sending large emails makes OE unusable Q: When I use oe to send an email of about MB to a netizen, the system prompts an error and cannot send it. Since then, oe cannot be used normally. It always displays "No email can be sent", but there is no error code. It can be sent after restart, but it will not work after a while, even if the mailbox is cleared, anti-virus, re-overwriting is still the case. What should we do? A: To avoid abuse of email servers and prevent spam and email bombs, the email system usually allows 2 MB to send each email ~ 10 MB. Therefore, when you directly send emails up to MB, problems will certainly occur. In this case, simply delete the email with a MB attachment from the sender. If OE still does not work correctly, you can export the account, Address Book, email, and other information after entering Oe. Then, open windows Resource Manager and clear the content in the/Microsoft/Outlook Express folder. Re-enter OE and then import the information. How to achieve multi-ISP line Interconnection Q: There are two Internet connection lines on the campus network, one is Netcom and the other is CERNET ). We plan to use a server (Windows 2003 and three NICs in the operating system) to share Internet connections to the campus network. That is to say, connect all three networks to this server, so that LAN users can freely access the campus network or telecommunication network. Can it be implemented? If this method is difficult, what is the best solution? A: In principle, this solution can be implemented. However, it is very troublesome and unstable to use a soft route configured by a common server. We recommend that you use a vro to implement this function. To achieve this function, the router must have an Ethernet port and two wide-area ports. The Ethernet port is connected to the campus network, and the two wide-area ports are connected to the CNC and CERNET respectively. The campus network uses the public IP address allocated by CERNET, sets a policy route on the router, adds all the IP addresses in CERNET to the access list, and sets Nat translation on the port connected to the CNC. When a campus network host accesses a host in CERNET, It is routed to the CERNET port. When a host in non-CERNET is accessed, It is routed to the CNC port and Internet access is achieved through NAT translation. IP address conflict Q: Recently, this problem often occurs on my computer. The system prompts "the IP address XXX. XXX is detected and the network hardware address 00053b0c12b7 has an address conflict. The network operation of this system may be suddenly interrupted. "Then, the network connection will be restored about one minute after the disconnection! What is the cause and how can this problem be solved? A: These system prompts are typical IP address conflicts. That is to say, the IP address used by the computer is the same as the IP address of another computer in the same network, resulting in communication failure. The MAC address of the NIC that conflicts with the computer is "00053b0c12b7 ". Generally, IP address conflicts are caused by improper IP Address allocation by the network administrator or unauthorized IP addresses. Because the MAC address of the NIC is unique, you can ask the network administrator to find the computer that is in conflict with you by using the MAC address and order it to modify the IP address. Run the "ipconfig/all" command to view the IP address and MAC address of the computer. Finally, use the "ARP-s IP address Nic physical address" command to bind the valid IP address to the MAC address of your Nic.

Reply: Always happy (posting: Level 5 member credit: 120 points: 2201) 2005-1-22 9:52:01 Vro-less shared Internet access Q: If you want to set up a LAN, you have the following restrictions: there is only one broadband line, and the operating system of each machine is Windows 98 SE, with a NIC configured. If there is no vro and the ADSL modem has no routing function, can seven machines share the Internet with only a hub? Can I set Windows 98 SE as a proxy server? A: No router or ADSL modem has no routing function, and only a hub can share Internet connections. Windows 98 SE can also be set as a proxy server for Internet Connection Sharing. For LAN with only seven computers, you can directly use the "Internet Connection Sharing" of Windows 98 SE, and there is no need to install other agent server software. For example, the host is equipped with two NICs, one connected to the ADSL modem, And the other connected to the office LAN. In addition, when setting Internet Connection Sharing, You must select the correct Internet connection, that is, you must use the broadband connection as an Internet connection, rather than the network adapter connecting to the ADSL modem. IE cannot display images Q: When I browsed the webpage, the displayed images suddenly failed to be seen and turned into a small white square with a red "X" on it ". To display an image, right-click the red "X" and select "show image. At the same time, the font of the webpage is also relatively large. My page settings are 1024x768 pixels. The font size is significantly greater than the default value. How can I solve this problem (ie version 5.01 )? A: We recommend that you use the SFC command to scan for System File Corruption. If yes, extract the intact file from the Windows installation disc and replace it. At the same time, IE6 SP1 can also solve this problem (this problem occurs frequently in ie5 versions ). You cannot access the Internet immediately after dialing ADSL. Q, however, "Local Connection" shows that data packets are always sent and received. You can access the Internet by changing the ADSL modem to another machine. Changing the NIC, formatting the system, and reinstalling Windows XP still won't work. Why? A: network hardware (nic and adsl modem) should be okay. In addition to host hardware problems, it may be because your system is infected with viruses, especially for Shock Wave viruses (data packets are sent and received for a long time and cannot be accessed because most of the bandwidth occupied by the data packets sent by the virus). If the Data Partition is not formatted during formatting, it will certainly be infected again. We recommend that you install system patches to completely eliminate viruses or use firewall software. There is a simple way to determine whether the fault is a machine hardware fault or an operating system fault: format a system partition with the Windows 98 boot disk and install Windows 98, and then install the ADSL dialing software. Other software is not installed. If the problem is solved, it is not the hardware fault of the machine (because the shock wave virus does not work for the Windows 98 System), the rest is the anti-virus, reinstallation of the system and patching work.

However, a user cannot access the Internet (the system is Windows XP) regardless of the adjustment ), after adjusting the working mode, there are only sent packets and no received packets. Why? A: almost all switches and network cards support 10/100 Mbps self-adaptation. That is to say, the switch or network adapter will automatically select the highest available communication rate based on the peer device, mbps full duplex, Mbps half duplex, 10 Mbps full duplex, and 10 Mbps half duplex. Therefore, the switch and the NIC can automatically negotiate the transmission rate without modifying the NIC configuration. If only the sent data packet is not received, the network is disconnected. That is to say, there is a problem with the connection link between the computer and the switch. Check the LEDs of the NIC and corresponding ports of the switch, or use the network cable test device to check the connectivity of the network cable to eliminate the network cable fault. If the network cable is correct, try to change the port of the switch. Finally, you can try to replace the NIC or change the NIC to another slot, which is most likely caused by hardware conflicts. Clear cookies and still directly log on to the website Q: because the public computer is used, cookies are deleted after use for insurance purposes. However, after logging on to some websites (especially forums and so on), even if all the cookies are deleted, you still cannot clear the logon information and re-open the website to find that you have logged on. Only by clicking "exit" on the website can the login information be clearly cleared. How can this problem be solved better?           A: Only cookies are cleared and logon information cannot be completely cleared. You must restart Internet Explorer. At the same time, the login information is not limited to cookies, but also the user and password information stored in IE, which requires attention. Upgrade the operating system to Windows 2000/XP, create a user and set a password for each user, and completely solve this problem (each user has different program settings ). Unable to enable Net Meeting Remote Desktop Service Q: Can I remotely access and manage NetMeeting Remote Desktop Sharing in Windows 2000 after it is enabled? I cannot enable the service on a machine. When I open the service, the system prompts "error 1053. The service did not respond to the startup or control request in time ". The system is Windows 2000 Professional Edition. Is it because of version relationship (not Server Edition )? How can this problem be solved? Answer: 1. Enable "Remote Desktop Sharing" to enable other users of NetMeeting to view your desktop. If "Accept control" is enabled when "Remote Desktop Sharing" is enabled, other netmeeting users can control your computer, but you will see the control result when controlling it. 2. netmeeting cannot be started on a single machine. It may be related to the network environment and protocol settings, or the system file is damaged. Run the SFC command to check the problem. 3. netmeeting can be used on Windows 98, Windows 2000, and other computers, whether professional or server. Remote Management between different operating systems Q: The LAN machine systems are Windows 98 and Windows 2000 Professional. in Windows 98, you only need to enable "Remote Management Service" in "password" of the control panel, enter a password on another host to remotely access all resources of the host. However, in Windows 2000, open "Network neighbors" and select a host. However, there is no "administrative program" in the property, in Windows 98, users cannot access non-shared resources in Windows 2000. How can this problem be solved? A: "Remote Management Service" is available only in Windows 95 (after Windows 95 Remote Management Service is installed) and Windows 98. It can only manage shared resources and cannot manage other content. You can use Terminal Services on Windows 2000/2003 Server and Remote Desktop on Windows XP to fully manage your computer. To remotely manage Windows 2000 Professional on different systems, you can install remote management software such as WinVNC and pcAnywhere. How to completely delete IPC $ share Q: I have a question about how to disable IPC $, modify the key value restrictanonymous in the Registry "hkey_local_mchihe/system/curronecontrolset/control/LAS" to "00000001" or "00000002" to disable IPC $. After I modify the file, run the net share command to check that the IPC $ share still exists. Why? A: IPC $ sharing is set for the management system. After it is disabled, it is automatically rebuilt when the machine is restarted next time. That is to say, the IPC $ share cannot be completely closed, which is required by the system. If you must completely disable IPC $ sharing, you can stop the Server Service in "Administrative Tools> services". However, all the shares in the system will no longer exist.

Reply: Always happy (posting: Level 5 member credit: 120 points: 2203) 2005-1-22 9:55:32 Why can shared Internet access be achieved without a route Q: In "expert session 16th", all clients and proxy servers use Windows 98 SE. However, Windows 98 SE does not support dual-nic routing. why can it achieve Internet sharing? How many NICs does the proxy server need? A: For non-route ADSL connections, Internet connections can only be shared through a Broadband Router or proxy server. When a Broadband Router is used, you can connect ADSL to the WAN port, connect the hub to the LAN port, and then set the Broadband Router. When a proxy server is used, the proxy server usually needs to install two NICs, one connected to ADSL and the other to the LAN Hub. When using Windows ICS (Internet Connection Sharing) for Internet sharing, you can use dual-nic. Although Windows 98 SE does not have the routing function, you can still use ICS to Implement Network Address Translation (NAT) to share Internet connections. In Windows 2000/XP, you can also use a bridge to share Internet connections. Map and manage LAN folders Q: How can I map folders in a LAN so that the same folder on all other computers can be changed dynamically no matter on which computer? How can I encrypt a folder on the network without using encryption software? How to assign a folder quota, that is, the space size of a fixed folder? A: You can map the shared resource to a network drive. In this way, when network resources change, all users with the right to access the shared folder will get the modified file resources. If you want to synchronize the shared folder with the data on the local hard disk for offline browsing, you can use the "Synchronize" function, enables the laptop to automatically synchronize resources shared with the server when it is connected to or out of the LAN. In Windows 2000 and Windows XP Professional versions, when using the NTFS file system, you only need to right-click the file or folder to be encrypted, and select "properties" in the shortcut menu ". Then, click the "advanced" button in the "properties" dialog box, select the "encrypt content to protect data" check box in the "Advanced properties" dialog box, and click the "OK" button in turn, encryption. Encrypted Files can only be displayed when the current user logs on correctly, thus ensuring data security. Note that Windows XP Home does not support encryption. In Windows 2000/XP/2003, when using the NTFS file system, right-click the volume to which you want to set the disk quota, and select "properties" in the shortcut menu ". Then, select the "quota" tab in the "properties" dialog box, select the "enable quota management" check box, select the "restrict disk space to" option, and specify the quota space. To specify different quotas for individual users, click the "quota items" button for detailed settings.   You cannot share resources when you enable the Guest account. Q: The computer in the office is a Windows XP operating system. Previously, the guest Guest account was enabled, and other computers in the LAN can access the shared folder. I don't know why. When I click the computer in "Network Neighbor", a message indicating no access is displayed. What should I do? A: We recommend that you follow these steps: First, check whether the guest Guest account is enabled in the settings of the current user (for example, the user name used for logon is different from the previous one. 2. confirm that the "Internet Connection Firewall" is not enabled for the connection to the LAN ". Third, Run "set up home or small office network" again to add the computer to the network. Fourth, reset the shared folder. Fifth, check whether the IP address information is correct. All network services except FTP are unavailable. Q: The internal LAN is connected to the Internet through ics of Windows 2000. Recently, it was found that Windows 98 workstation can only be downloaded through FTP, but Audio/Video On Demand and QQ cannot be used. All Internet services in Windows 2000 fail. What should we do? A: Internet Connection Sharing is irrelevant to the client operating system. Since Windows 98 can use the FTP service, there is no problem with the Internet connection. Therefore, the fault location should be limited to the ICS host and client. The following steps are recommended: First, check whether the DNS settings of the ICS host are correct. When an error occurs in DNS settings, only Internet services that can be accessed through IP addresses are normal. Second, ICS hosts provide DHCP services at the same time. Therefore, computers in the network should automatically obtain IP addresses to avoid network failures due to incorrect IP address information. Third, because ICS implements Internet Connection Sharing by means of address ing, clients and all Internet applications do not need to make any settings, just as they connect directly to the Internet. Fourth, run the ipconfig command in Windows2000 to check whether the IP address is "192.168.0.x". If the IP address is "169.254.x.x", it indicates that the network cannot be correctly connected. Check the connectivity of the network. Fifth, check whether the ICS host has installed a firewall and has blocked services other than the FTP service.

Reply: Always happy (posting: Level 5 member credit: 120 points: 2204) 2005-1-22 9:58:18 Users in the LAN cannot access the Internet. Q: there are 20 PCs and 5 laptops in the office to access the Internet. The network has been configured. The server runs Windows 2000, enables DHCP, DNS, IIS, and SQL2000 services, runs OA and web servers, and installs dual NICs. Because the company does not use a static IP address for the time being, it uses the Internet connection shared by the ICS of ADSL + Windows 2000. LAN access to the Internet is very slow. Sometimes you need to refresh the page several times to open the webpage. Ping the LAN is normal. Sometimes the times and TTL values are returned normally when the LAN is pinged, but the webpage cannot be opened. How can we make the LAN faster? A: try to solve the problem from the following aspects: First, if DHCP and other network services and SQL database services are all concentrated on one server of the proxy server, the system will be overloaded, and the efficiency of Internet Connection Sharing services will be greatly reduced, as a result, the Internet connection rate is greatly reduced. We recommend that you disable unnecessary services or configure services with high system resource requirements on other machines. In addition, check whether the machine is infected with the worm. Second, the Internet Connection Sharing efficiency of Windows 2000 is not very high. It is only applicable to small-scale scenarios. If the number of machines is large, we recommend that you use NAT in Windows 2000 or ISA Server as the proxy server, and use proxy software such as Wingate and Sygate. This is a frequently asked question about Internet Connection Sharing using Windows 2000. Third, try to test the Internet connection speed on the proxy server. If the connection speed on the proxy server is also very slow, contact the ISP to change the ADSL link or ADSL modem. Fourth, check whether the local area network's cabling device works normally and restart the switch. USB dual-host interconnection settings Q: One Laptop (with a single Nic in Windows XP) and one desktop (with a single Nic in Windows 98 and broadband access to radio/TV) are connected to the Internet using a USB cable (USB with software. Windows XP system can see Windows 98 shared files, but not vice versa. Lan games can only be added to games created by Windows 98 machines on Windows XP machines. How should I set up sharing? Can I use the bridge settings of the USB connector? Can I connect to a machine with a network cable (each machine has only one network card) and access the Internet at the same time? A: First, if you want to share files in Windows XP and a normal connected game on Windows 98, you must perform two operations on Windows XP. First, enable the anonymous guest account, and second, run the "Set Home or small office network" Wizard. Second, you can set bridging in the desktop to facilitate information exchange. The USB connection line can be regarded as a local network, and the NIC connected to cable modem can be regarded as an Internet connection. Then, the Internet connection between two machines can be shared by means of bridging. Third, only one network card on each computer cannot achieve Internet Connection Sharing, unless the cable modem or ADSL modem is a USB interface or built-in. Therefore, the second Nic should be installed on the desktop, one connected to the laptop and the other to the cable modem. Then, set Internet Connection Sharing on the desktop. Access failure due to firewall conflict Q: Windows xp ics shared Internet connections are used in the LAN. The host is equipped with the rising anti-virus software version 2004 and the rising firewall, and the Internet Connection Firewall is also enabled. The computers in the network share the Internet through the host. The operating system is win/98/2000/XP. It is installed with the anti-virus software version 2004 and the rising firewall, and the system Internet firewall is enabled. The IP address of the host is 192.168.0.1 and other machines are 192.168.0.x, the Working Group is the same as mshome, And the subnet mask is the same as 255.255.255.0. Although the ICS host can access the web site normally, other computers in the LAN cannot. Why? A: You can troubleshoot the problem in the following ways: First, only one network firewall can be enabled on the winxp ics host, and neither the rising firewall nor the Internet Connection Firewall can be enabled at the same time. Disable the Internet Connection Firewall. Second, the LAN client cannot enable the firewall, whether it is the rising firewall or the Internet Connection Firewall. Otherwise, resource sharing and Internet Connection Sharing will fail. Try to close all the firewalls, and the problem may be solved.
